Answer 2

Question:-

A car drives 120 kilometres in 3 hours. Calculate the average speed, in km/h, of the car using the formula: Speed = d÷t.

To find:

• Speed of car in km/h

Given :

• Distance = 120 km

• Time = 3 house

We know:-

$\bigstar \boxed{ \rm Speed = \frac{distance}{time} }$

So:-

$\dashrightarrow \sf Speed = \dfrac{distance}{time}$

$\dashrightarrow \sf Speed = \dfrac{120}{3}$

$\dashrightarrow \sf Speed = \cancel\dfrac{120}{3}$

$\dashrightarrow \bf Speed = 40 \: kmh {}^{ - 1}$

$\therefore \underline {\textsf{\textbf{Speed of car is equal to \red {40km/h}}}}$
